Title: Composition and process for making porous articles from ultra high molecular weight polyethylene
Inventor: STEIN HARVEY L
IPC: C08J9/00
Filed: 1989-03-16
Granted: 1995-05-23
Abstract: Porous shaped articles made from a molded composite of ultra  high   molecular   weight   polyethylene   and polyethylene wax are disclosed.   These articles are produced by  free-sintering  a non  intensively mixed blend  of  UHMW-PE  particles  and  particles  of  a polyethylene wax.   The process  involves  mixing  the UHMW-PE  and  wax  both  in  powdered  form  until  a heterogeneous mixture is formed, but under conditions which do not lead to any substantial fracturing of the UHMW-PE particles or melting of either component.  The heterogeneous mix is then transferred to a press mold to form a shape and pressure is applied sufficient only to maintain the enclosed volume of the shape.  The mold is heated to a temperature above the melting point of the UHMW-PE for a period of time to allow the particles to soften,  expand,  and contact one another at their surfaces.  The mixture is then quickly cooled.            Porous  articles  so  produced  may  exhibit  stiffness values in excess of about 2000 psi while at the same time showing excellent porosity values of less than about 25 inches water pressure drop.

Title: Digital 2b1q transmitter with high precision and linearity time domain response
Inventor: WONG HEE
IPC: H04L25/49
Filed: 1989-06-02
Granted: 1992-11-24
Abstract: Abstract WITH HIGH PRECISION AND LINEARITY        TIME DOMAIN RESPONSE      A digital 2B1Q transmitter utilizes a dual modulator to generate a 2B1Q coded output by summing two binary modulated vectors in a 2:1 weighting ratio, allowing one modulating envelope generator to drive the dual modulator.  The modulating envelope is coded in a 1-bit pulse density modulation (PDM) format, permitting the use of simple gating functions in performing the modulation function.  The rising half of the transmit pulse is stored in the envelope generator, while the trailing half is derived from the rising half using the "1-x" function; this allows part of the summing functions to be reduced to OR gates.
